Pallette Class Help

[Lying]

Hi<BR> I want to generate dynamic image on web server for that i create image streame and I draw some grafic on that image. now when I save that image as gif on server or send that to user the file size is big, this is due to fact that in spite of me using only 5 colors in my image it uses 224 color pallette, I searched msdn but cant find any sample to guide me how to use my own color pallette. or how to use Colorpallette class to create image with defined pallette that uses only limited colors.<BR><BR>thanks in advance
